Recent Results on Fusion of Effective Retrieval Strategies in the Same Information Retrieval System
[chapter]
2004
Lecture Notes in Computer Science
Preserved Fulltext
We show that this is not the case when systemic differences are held constant and different highly effective document retrieval strategies are fused within the same information retrieval system. ...
Although the precise conditions necessary for fusion to improve retrieval have not been identified, it is widely believed that as long as component result sets used in fusion have higher relevant overlap ...

We hold constant systemic differences such as parsing, stemming, phrase processing, and relevance feedback, and fuse result sets generated from highly effective retrieval strategies in the same information ...
Although these improvements have been observed from the fusion of result sets from several distinct information retrieval systems, it has often been thought that fusing different document retrieval strategies ...

In recent years, multimodal fusion has emerged as a promising technology for effective multimedia retrieval. ...
Given a query, existing methods derive a unified fusion strategy for all documents with the underlying assumption that the relative significance of a modality remains the same across all documents. ...
However, since different queries have different information needs, using the same fusion strategy generally results in low retrieval accuracy. ...
